Key Takeaway:
- Wild fermentation is a natural, spontaneous process that relies on naturally occurring yeast and bacteria to ferment food and drinks. Controlled fermentation, on the other hand, is a process that involves the use of specific strains of yeast and bacteria, and strict temperature and time controls to ferment food and drinks.
- The main difference between wild fermentation and controlled fermentation lies in the unpredictability and uniqueness of wild fermentation. While controlled fermentation yields consistent and standardized products, wild fermentation produces varied and distinct flavors and textures that can vary depending on environmental factors and regional microorganisms.
- Factors such as temperature, humidity, and the presence of airborne microorganisms can influence the success of both wild and controlled fermentation methods. However, wild fermentation does require more attention and monitoring to ensure proper fermentation and avoid spoilage.
Fermentation is a complex process vital to create some of our favorite drinks and foods. You may be asking yourself, “What is the difference between wild fermentation and controlled fermentation?” In this blog, we’ll dive deeply into the answer and explore both fermentation methods.

Understanding Fermentation
Fermentation is a process that has intrigued mankind for centuries. It is the transformation of organic substances such as sugars and carbohydrates in the presence of microorganisms like bacteria, yeast, or fungi to produce energy, alcohol, or other beneficial compounds. To understand this process, it is essential to differentiate between wild fermentation and controlled fermentation.
Controlled fermentation refers to the process in which microorganisms are added intentionally at specific stages of fermentation, and aspects like temperature, pH levels, and nutrient availability are monitored. In contrast, wild fermentation occurs spontaneously, relying on the microorganisms that exist naturally in the environment to initiate the reaction.
Both wild and controlled fermentation can be used to create a broad range of products such as beer, wine, cheese, bread, and kimchi. The primary difference is that in controlled fermentation, the process is predictable, and the results are consistent. In contrast, wild fermentation can be unpredictable, and the outcome is dependent on a variety of factors such as temperature, humidity, and the microbial population present in the environment.
It is worth mentioning that while wild fermentation may not provide a consistent product, it can result in unique flavors and nutritional benefits that are not achievable through controlled fermentation. For example, sourdough bread made with wild yeast tends to have a more complex flavor profile and easier to digest.
A true fact is that fermentation is not a new concept and has been practiced for thousands of years. Ancient civilizations such as the Egyptians, Greeks, and Chinese used fermentation to preserve food and create new flavors. In fact, there is evidence that beer was being produced in ancient Mesopotamia as early as 3500 BCE.

Wild Fermentation
Gain insight into wild fermentation! This article looks at its definition, process, and examples. Get an understanding of how to ferment without outside help and what types of food this method works on. Check out the sub-sections for a closer look!
Definition and Process of Wild Fermentation
Wild fermentation is an innovative way of fermenting food and beverages using naturally occurring bacteria, yeast, and other microorganisms. This method weaves its magic slowly, in contrast to the controlled fermentation process, which uses specific strains of microorganisms under regulated conditions.
Here’s a 4-step guide to Wild Fermentation:
- Start by preparing your chosen produce (veggies or fruits), washing them thoroughly.
- Cut them into small sizes to speed up the fermentation process and layer them in a clean container.
- Add salt or water brine as per your recipe, or leave it be if you’re using a high-moisture veggie like cabbage.
- Cover the container with a cloth or lid that allows air to escape. Store it in a cool, dark place for at least 2-3 weeks to ferment.
Wild fermentation preserves beneficial bacteria that can enhance gut health while adding unique flavors to foods. Foods fermented through this method tend to have increased nutritional value.
Pro Tip: Avoid sending too much oxygen during the fermentation process; this may invite the growth of undesirable molds on top of your preserved food.

Examples of Wild Fermentation
Wild Fermentation: Distinctive Examples of Spontaneous Fermentation
Wild fermentation happens when bacteria and yeasts found naturally in the air, on our food, skin, and gut create a transformative change to our fluids, causing fermentation. Here are some examples of wild fermentation:
- Sauerkraut: A combination of tomatoes, carrots or cucumbers that ferments through lactic acid bacteria for sourness
- Kefir: Kefir grains consist of bacteria and yeast that ferment milk to become creamy
- Kimchi: Korea’s spicy staple with fermented cabbage, garlic, and ginger-hoses lactobacillus culture for zinginess
- Yogurt: Bacteria strains transform warm milk into creamy texture
- Miso Soup: Soybean paste is transformed by fungus
- Sourdough bread: The symbiotic relationship between yeasts and bacteria gives sourdough its tanginess
These wild-fermented foods have distinctive flavors, textures and nutritional benefits. However, it’s essential to be mindful of hygienic practices during preparation as wild fermentation can promote unwanted microbial growth.
Historically speaking, wild fermentation predated controlled fermentation techniques like beer brewing and wine-making by over 1000 years. Before commercialized production consumed the industry’s standards, reliance on natural bacterial cultures allowed people to store their crops for longer periods or make medicinal tonics from malty water.
Controlled fermentation is like having a helicopter parent, while wild fermentation is more like a free-spirited aunt who lets you make your own mistakes.

Controlled Fermentation
Gaining insight into the benefits of controlled fermentation? Let’s define it and learn its process! Examples of this type of fermentation will be shown. Mastering it will give you consistent and reliable results. Get to it!
Definition and Process of Controlled Fermentation
Controlled fermentation is a process of fermenting food or drinks in which the environment, temperature, and other factors are carefully controlled to achieve a specific outcome. Unlike wild fermentation where natural microorganisms are allowed to do the work, controlled fermentation employs artificial starters or yeast to control the fermentation process. It results in consistent, predictable outcomes with minimal risk of spoilage.
In controlled fermentation, the conditions are calibrated based on the desired outcome. For instance, yeasts can be added early or late in the process and at different intervals to achieve nuanced results like aroma and flavor variations. Similarly, temperature variation can also lead to differences in finished products. The process requires precision measurement and control of environmental variables for optimal results.
Notably, controlled fermentation extends beyond controlling external temperature but also managing internal ecological conditions such as pH levels and nutrient inputs to ensure all microbes thrive remains stable throughout the entire period of fermentation. Therefore, it may require more equipment than wild fermentation processes but consistently yields specific flavors regardless of seasons and other uncontrollable factors.
For those interested to delve into controlled fermentation as a hobby or make a career out of it, we suggest acquiring basic knowledge about relevant scientific principles involved in microbial growth & design equipment that suits any particular process- e.g., airflow vents – that enables oxygen flow or limits microbial contamination while enhancing desirable chemical reactions. What’s more, understanding standard practices observed by well-known players already obtaining remarkable yield like intuitive sanitation routines also plays a big role.
Get ready to see some serious control freaks in action as we dive into examples of controlled fermentation.
Examples of Controlled Fermentation
Controlled Fermentation entails regulating and monitoring the conditions for fermenting food and drinks, unlike Wild Fermentation centered on natural fermentation. Here are some variations of Controlled Fermentation processes with their peculiar conditions illustrated in a table.
| Type of Fermentation | Example Food or Drink | Temperature Range | Time Duration |
|---|---|---|---|
| Lactic Acid Fermentation | Yogurt, Kimchi, Sauerkraut | 15-30°C (59-86°F) | Few Hours to Months |
| Yeast Fermentation | Beer, Wine, Bread | 20-25°C (68-77°F) for bread; 15-25°C (59-77°F) for beverages | Few Days to Months |
| Acetic Acid Fermentation | Vinegar, Kombucha* | Broad Range based on Microbes in Use. e.g., Acetobacter spp., Gluconacetobacter hansenii can work at temp as low as 10°C(50°F), while Komagataeibacter rhaeticus works best at around 30 °C(86°F). | Few Weeks to Months |
*Note: Kombucha is usually fermented first by yeasts then in the SCOBY by bacteria like Acetobacter spp.
Some examples not captured in the table include Tempeh production and sausage making.
Pro Tip: When fermenting foods or drinks using controlled fermentation methods, it is essential to keep proper records of the duration and conditions during fermentation for future reference.
Don’t let your ferment go rogue, keep it under control with the right technique.
